That simulated image is quite cool, but can you imagine what a night sky like that would have done to world religions?

While that's true, this article is about a journal article published in Nature.

Here's the link to the article in Nature.

Naturally aspirated engines also rely on the density of the atmosphere for their efficiency. At sea level, they produce full power, but as you go up in elevation they decrease power substantially. It's pretty much impossible to sustain combustion alive 12,000 feet without using a turbocharger or a supercharger. While that's not necessarily a major problem for cars, it's a huge problem for airplanes with reciprocating engines. There are lots of small aircraft with turbochargers as a result.

It was subtle, but it was on purpose :)

Attraction is more of a chemistry thing than a physics thing.

Those magical girl transformation scenes are going to look a little weird in PE class.

You're never too old to get scolded by your mother.

That might actually make Bing worth using.

I suddenly have an urge to visit a planetarium.

I smell a business Opportunity.

The phrase you're looking for is "bubble nucleation." Bubbles don't really just form spontaneously. They need something to start the process, after which they grow larger until they are big enough to float upward. If there's a single place where they seem to form more consistently, it's because there is something different about that spot. Most likely, there's a small irregularity in the glass there... probably a small bump. That irregularity makes it easy for bubbles to form.

In a similar vein, when you're doing lab chemistry, there are many chemicals you want to boil in the most controlled way possible because they're dangerous if they get out of control. One way to do that is to deliberately introduce something into the beaker that will allow the bubbles to form smaller, faster, and more easily. "Boiling chips" are added to accompany this. They are small pieces of an inert substance that have lots of edges and points (much like the glass irregularities in the champagne bottle or cup that you observed.)

Here is a YouTube video that shows some boiling chips in action.

"So how did you get tetanus?"

"Well, my toilet seat broke."

"Dude, you can't get tetanus from a broken toilet seat."

"That's what I thought! Clearly, I should have seen it coming!"

The older I get, the more I think that capitalism and insurance are a terrible mix.

This looks fantastic. It also makes me feel very small.

There's at least one scientist saying that Europa has little surface radiation. I really want to see this published.

Here's a little preview of what the night sky will look like as Andromeda merges.

I would love to see it in person though. Especially that third panel from the top on the left.
